Plasma welding is not a new process to the industry, but only in the past few years has it gained significant acceptance. Until recently, the process was considered exotic and difficult to understand. This was mainly due to the applications it was being adapted to. PLASMA NOW HAS PROVEN ITS VALUE IN THE AREA OF HIGHLY REPETITIVE AUTOMATED WELDS. THE PROCESS PROVIDES INCREASED RELIABILITY AND REPEATABILITY TO MEET TODAY’S HIGH STANDARDS OF PRODUCTIVITY.
It is most frequently used as an alternate to the gas tungsten process (GTAW) . For most applications, the plasma arc process offers increased electrode life, reliable arc starting, improved arc stability, better penetration control and reduced current levels. In some cases, plasma offers increased travel speeds, improved weld quality, and less sensitivity to operating variables.
